To all whom it may concern."

Be it known that I, Cnns'rnn E. MACDUFFEE, a citizen of the'United States, residing at the borough of Manhattan, city, county, and

State of New York, have invented an Improvement in Means for Holding and Con- My invention relates to a means for holding and conveying the air tubes and electric conductors to submarine diving armor in such a manner as to avoid such difiiculty and danger, and consists of a single continufl ous and seamless tubing within which the air tubes and electric conductors are contained and carried to the armor, to which the air tubes are connected by means of a peculiar attachment, permitting a free movement of the tubing at this point. This attachment however, forms the subject matter of-a separate 00- ending application filed December In the accompanying drawing :--Figure 1 is an elevation of the upper part of, an armor for submarine divers, illustrating how my invention is applied to the same. Fig.-

2 is an elevation in larger sizeand at right angles to Fig. 1 ofa portion of the part shown in said figure. Fig. 3 is a section in larger size at the dotted line :12, m, Fig, 2,

looking downward. Fig. 1 is a similar view r at the dotted line y, y, of Fig. 2 looking upward, and Fig. 5 isa section at line a, z, of Fig. 3.

the dotted Similar reference numerals-refer to like .parts throughout the several views:

1 is a seamless tubing of any ,desired length, made up of two or more concentric seamless tubes of rubberized canvas or other suitable material all vulcanized together.

This'tubing is preferably oblong in cross secgreat danger from such tion so as to present faces.

2 is an air-tight tubing of flexible char;

flattened opposite '1 slinacter through which air is supplied to -t-he\ 55 diver, and 3 is a similar tubing through i which exhaled or vitiated air is conveyed from the armor arid discharged into the atmosphere above water.

4 4: represent electric conductors for con- 9 At or near the lower extremity of the tubing.1 the air tubes and electric conductors emerge therefrom in three branches, 10-, 11 and 12. The branch 10 containing the.electrio conductors 4 4 and 6 6 is "carried into the armor 8 through a suitable bushing l3;

the branch 11 representing the air supply tube2 and the branch 12 the exhaust tube 3.

These branches 11 and 12 are each provided at their outer ends with a screw-threaded coupling nut 14 which are to be screwed upon the screw-threaded ends of tubular cylindrical members 15 projecting from a cylinder 16 attached to the armor 8.. These tubular members 15 have a swinging moverhent which allows play to the air tubes while the diver is descending or ascending or s .at work at the bottom, and prevents any on due strain upon the tubes at such times.

It will be readily understood that by my improved 'means of holding and carrying the airtubes and electric conductors all danger-or undue strain is avoided, and the fiattened shape of the carrying tube facilitates the proper winding 'or unwinding of the same upon a reel, which I, propose to employ i in its manipulation.
